Why do I get different results among the ANOVA Module and the Visual General Linear Models module when I run the same type of analysis on the same dataset?
The ANOVA module works off of variable selections differently than does the Visual General Linear Models(VGLM) module. Specifically, the ANOVA works off of the variable numbers, and VGLM (or any other Visual module) works off of the Syntax editor. When you specify the variables in the dialog box in the ANOVA module, use the number values for the variables. For instance, when you choose variable 67, named Average, it uses the 67th variable in the data file for the code. When the variables are specified in VGLM, the syntax editor will refer STATISTICA to the NAME of the variable. In our above example it will read as Average, NOT necessarily the 67th variable. To see this occur, if you go to the Syntax Editor you should note that it denotes variable names, not numbers. It has been created this way to make it easier for the user to customize this Editor for designs. Please note that this also means your data file cannot have multiple variables named with the same word. When you run a data
